CVE-2026-64464

Consolidated details show CVE-2026-64464 affects the Linux kernel xhci sideband path: xhci_ring_to_sgtable() allocates a temporary pages array used to build an sg_table via sg_alloc_table_from_pages(). On success, the temporary array isn’t freed, causing a leak each time a sideband client uses an...

CVE-2026-64302 x86/mm: Fix freeing of PMD-sized vmemmap pages

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Fix freeing of PMD-sized vmemmap pages Commit bf9e4e30f353 "x86/mm: use pagetablefree", switched from freeing non-boot page tables through freepages to pagetablefree. However, the function is also called to free vmemmap...

CVE-2026-64302

Summary: CVE-2026-64302 affects the Linux kernel in the x86 memory management code. The root issue is that pagetable_free() was used to free PMD-sized vmemmap pages, but vmemmap pages are not page tables, causing only the first page to be freed and leaking the rest. This was triggered by a commit...

CVE-2026-64297 module: decompress: check return value of module_extend_max_pages()

In the Linux kernel, the following vulnerability has been resolved: module: decompress: check return value of moduleextendmaxpages moduleextendmaxpages calls kvrealloc internally and returns -ENOMEM on allocation failure. The return value is never checked. If the initial allocation fails,...

CVE-2026-64297

Summary (CVE-2026-64297): The Linux kernel vuln arises from not checking the return value of module_extend_max_pages() inside the decompression path. When initial allocation fails, info->pages is NULL and info->max_pages is 0. Subsequent calls to module_get_next_page() may call module_exten...

In the Linux kernel, the following vulnerability has been resolved: fpga: dfl-afu: validate DMA mapping length in afudmamapregion afuioctldmamap accepts a 64-bit length from userspace via DFLFPGAPORTDMAMAP ioctl without an upper bound check. The value is passed to afudmapinpages where npages is...

CVE-2026-64280

The CVE concerns the Linux kernel’s FPGA driver for DFL FPGA management (fpga: dfl-afu). A 64-bit length passed via the DFL_FPGA_PORT_DMA_MAP ioctl to afu_ioctl_dma_map() can overflow when computing the number of pages (length >> PAGE_SHIFT) passed to pin_user_pages_fast(), since npages is ...
